Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the

abuse. In their experiment‚ Anttila et al. (2008) tested if testosterone can regulate the aerobic capacity of skeletal muscles by injecting mice with certain amounts of testosterone and then studying the levels of myoglobin‚ a protein that plays a role in supplying oxygen to mitochondria during exercise. They demonstrated that the myoglobin concentration in skeletal muscles is directly related to testosterone. Therefore‚ an increase in testosterone will allow for more muscular potential. In addition

BENEFITS OF EXERCISE? Physical exercise is very important for a healthy body. To stay healthy and fit‚ we need to exercise regularly. Most people believe that exercise and work are the same. They believe that if they exert effort‚ flex their muscles during work‚ it is already an exercise. But exercise and work are not the same thing. Although both expend energy‚ exercise has an element of pleasure. When you work‚ you become tired‚ the same as when you exercise. But in exercise‚ there is a sense

within living tissue by touching the muscle of one with the nerve of another and causing muscular contraction. His theories were widely accepted but disputed by Alessandro Volta. Alessandro Volta was a professor of physics and proved the inaccuracy of Galvani’s theories by showing that electricity wasn’t produced as a result of animal tissue but in fact it was only present due to the electricity being conducted by the two metals due to the moisture in the muscle tissue. Hence he deduced that electricity

into the muscle. This is caused by an enzyme called creatine kinase. ADP is the result of this chemical reaction (adenosine di-phosphate). The resulting energy is used to regenerate ATP from ADP and another free phosphate. Lactic Acid System Like the creatine phosphate system‚ the lactic acid system also is a short term and high intensity energy system. Glycogen which is stored in your muscles is broken down into glucose to be used as an energy source for the contractions in the muscles. ATP plays

MUSCULOSKELETAL ASSIGNMENT 2016 Hinge Joint- Knee The knee joint is the largest joint in the body‚ consisting of 4 bones and an extensive network of ligaments and muscles. What is the scientific name of this joint? The knee joints that make up the knee are split into three parts. The femur meets the tibia to form the main knee joint. This joint has an inner called medial and an outer called lateral compartment. The patella joins the femur to form a third joint‚ called the patellofemoral joint. The

Athletes may have several reasons for using performance-enhancing drugs. An athlete may want to: build mass and strength of muscles and/or bones; increase delivery of oxygen to exercising tissues; mask pain; stimulate the body; relax; reduce weight or hide the use of other drugs. Athletes use anabolic steroids because they increase muscle strength by encouraging new muscle growth. They allow the athlete to train harder and longer at any given period. However‚ there is no coherent argument to support
